This is CircuitPython 6.0.1, the second 6.0.x stable release. This release fixes regressions in BLE and
FrequencyIn() that prevent these functions from operating properly. The release also includes a considerable speedup in JSON parsing.
Download from circuitpython.org
Downloads are available from circuitpython.org. The site makes it easy to select the correct file and language for your board. The downloads page is here. Downloads are no longer available from the GitHub release pages because of the large number of files for each release. (If you see the unstable release 6.0.0-rc.2 when you browse circuitpython.org, that release is older. Use this one.)
Try the latest version of the Mu editor for creating and editing your CircuitPython programs and for easy access to the CircuitPython serial connection (the REPL).
CircuitPython has a number of “ports” that are the core implementation for a variety of microcontroller families. Stability varies on a per-port basis. As of this release,
stm for the F4 family are stable.
stm for other chip families are being actively improved but may be missing functionality and have bugs.
mimxrt10xx are in an alpha state and will have bugs and missing functionality.
Fixes and improvements since 6.0.0
s can be zero. Better argument validation forstart_scan()
andstart_advertising()`. #3861. Thanks @dhalbert.
frequencyio.FrequencyIn()caused a crash. #3867. Thanks @dhalbert.
json: Speed up parsing dramatically. #3728. Thanks @tannewt.
Breaking changes since 5.x
i2cperipheraland the class in it is changed as well.
stopkwarg has been removed from
I2C.writeto(). If no stop is desired, then use
- The default speed of
board.I2C()is now 100khz, not 400khz as before. Use
busio.I2Cto set the speed explicitly.
_bleio.ConnectionErrorhas been removed. Code will now raise the native
audioio. They are now only available in
audiocore. 5.x has them in both modules.
